[5] Oral tradition has brought a story to the present day, about a deaf-mute shepherd boy from Avezzano to whom, while pasturing the flock on Mount Salviano and gazing at the waters of Fucino, the Madonna appeared dressed in white on a mule.

The shepherd boy came down running from Mount Salviano, and as soon as he reached Avezzano went to the parish priest, whom he told what the Holy Virgin had recommended, that is, to restore the Church of Saint Mary and worthily replace the sacred image onto the altar.

The Chapel of the Apparition situated along the via Crucis on Mount Salviano preserves the print that the Madonna's mule carved in the stone with a blow of his hoof before disappearing with the Virgin.

[10] In August 2018 it was announced that Capuchin Friars would not run the sanctuary anymore, due to the growing organizational difficulties related to the monks' old age and the reduction in the number of vocations.

Attached to it the Domus Mariae (Latin: "House of Mary") stands, built in the 1950s and used for spiritual retreats, whose care is entrusted to Benedictine Sisters of Charity.

Some frescoes reproduce the scenes of the miracles performed by the Virgin; outstanding is the large original painting depicting the Madonna and Child placed in an onyx niche on the end wall of the apse.
